I was reading the Power Rangers wiki page on Lord Drakkon and it said that Drakkon (Tommy) killed Rita when he won. So where's Lord Zedd or the Machine Empire or the space pirates from Turbo or The rest of the Alliance of Evil from the Zordon Era... Also when Drakkon killed Zordon why didn't it cause the Z wave that wiped out the Alliance of evil like when Zordon was killed in the ending of 'in Space'.

Will these questions be answered in or after Shattered Grid if at all?

I think I read that they explained alternate zordon was cut off from his tubule ro the grid so it didn't explain the wave
